LCD splicing screens can be used as standalone displays or as large screens. Variable large and variable small screens are available according to different use requirements: split screens, separate screens, arbitrary combination displays, full-screen LCD splicing, double-screen LCD splicing, image frame compensation or masking, digital signal roaming, zooming, stretching, cross-screen display, Various display plans can be set up and operated, and full-HD signals can be processed in real-time.
LED displays with a small spacing are those with LED point spacing of P2.5 and below, including P2.5, P2.083, P1.923, P1.8, P1.667, P1.5, P1.25, P1.0 and others.
How do LCD splicing screens differ from LED display screens with small spacing? Would you like to know the seven differences between indoor and outdoor LED displays?
1.Differences in technology
Principles of display
LCD LCD splicing screens belong to backlight+LCD imaging, and LED displays with small spacing belong to self-illumination. The LED display screen with small spacing has no seam, and the LCD LCD splicing screen gap is 0.88-3.5mm.
Saturation of colors
The color restoration and brightness of small-spaced LED displays are higher.
LED display screens with small spacing are 16bits, while LCD splicing screens are 8bits.
Consumption of energy
Energy-saving LED display screens and LCD LCD splicing screens have small spacing.
2.Thickness difference between products
LCD splicing screens are much thicker than small-space LED displays, and small-space LED displays have reached ultra-thin designs now.
A small spacing LED display screen all-in-one machine has an ultra-narrow frame of only 3mm, and an ultra-thin structure with an overall thickness of only 38.5mm.
3.Difference in cost
Currently, there are three main costs. A purchase cost is the first cost, a maintenance cost is the second cost, and a service life is the third cost.
Cost of purchase
LCD splicing screens are new and more competitively priced. Costs associated with maintenance;
Costs associated with maintenance
Small spacing LED devices only need to repair the broken module separately, which does not affect use, and maintenance costs are low; LCD splicing screens: most faults cannot be repaired, and only the whole screen can be replaced;
A small spacing LED display screen has a normal service life of 100000 hours, and an LCD splicing screen has a normal service life of 40000 hours.
Users need not worry about insufficient brightness with LCD panels and LED panels. High brightness and small spacing LED display screens, however, face the problem of high brightness. The display environment must be considered before choosing LED display screens. According to the needs of users, LCD manufacturers designed displays with brightness levels of 500cd/m2 and 700cd/m2, which make 55-layer LCD displays much more useful than LED displays.
In recent years, LED splicing screens have made great strides, but they still cannot compete with LCD screens. The resolution of LCD displays is generally 1920 x 1080p, and some LCD displays can already display 4K video. In order to achieve a higher resolution, it is necessary to increase the geometric base, reduce the pixel distance by 50%, and increase the base plate density by four times. In spite of bottlenecks at 1.0, 0.8, and 0.6, the real reason for a large number of applications is products like 3.0/2.5. Of course, this does not mean that clearer users cannot use it. Most users only use the splicing screen at ordinary resolution. In general, the higher the clarity, the more difficult it is to overcome this technology, and the more expensive the equipment is. As a result, many users do not choose high resolutions.
4.Display functions differ
Despite the fact that LED and LCD displays are mosaic screens, most of which are controlled by display controllers, their display functions are completely different. When the signal source is LED display, for example, the window can be realized by the processor roaming and multi-screen display at the same time.
In addition to supporting single-screen display signals, single-screen splicing multichannel signals, cross-screen splicing and roaming display effects, the Lot splicing screen can also be fused into a large screen display. Multiple signal sources of a single signal source can be displayed at the same time and decoding display can be achieved.
5.Maintenance methods differ
LCD splicing screens generally operate in post-maintenance mode – maintenance access is reserved at the back. Maintenance access must be left about 70cm to 1m wide at the back of the screen, which requires high construction space and will reduce visible space to a certain extent.
LED display all-in-one machine with full front maintenance, support hot plugging, no need to reserve maintenance channels, convenient maintenance, space saving, full front maintenance.
6.The environment in which the product is used varies
Since LCD splicing screens contain many electronic components, they can only be used indoors. As with all electronic products, it does not have waterproof characteristics, so it can only be used indoors in dry environments.
Because of its special structure, the small spacing LED display can be used indoors or outdoors. After adding waterproof measures, it can be used outdoors.
